copyright: update for the debian/ subdirectory
This is based on information obtained with `hg churn` excluding
the changelog and contributions that merely changed an outdated reference URL.
Also, it seems fair to keep Logilab in the list, as they cleary where employing
all the people involved in the initial effort, and they are sponsoring current
effort to include it in Debian itself.
